Phys.org / An ecosystem never forgets: Extreme heat and drought responses linked to hydrological memory

The low-latitude highlands region of southwestern China experienced two major climate events in recent years: a severe drought in 2009–2010 and an extreme heat wave in 2019. Though both sprang from similar large-scale atmospheric ...

Medical Xpress / Key brain cell 'hubs' found to synchronize the body's internal clock

What makes someone a "morning lark" or a "night owl?" Why does jet lag hit us so hard, and why do some people struggle each winter with seasonal affective disorder? Clues to these puzzles may lie in a tiny brain region called ...

Phys.org / Ancient sea anemone sheds light on animal cell type evolution

One of the biggest quests in biology is understanding how every cell in an animal's body carries an identical genome yet still gives rise to a kaleidoscope of different cell types and tissues. A neuron doesn't look nor behave ...
